The aperture and ange are preferably circular in outline. Surroundingtheaperture ,the bowlis preferably beveled, as: at I8.4 Fitted within theaperture andextending forsome distance below the LbowLisa drainmemberI9, the upplend of which is y provided with an outwardly-turnedVi'iangewhichrests upon the bevel IBand forms a `water-gtiglit jointtherewith. (At its lo'wer end, the member-119 istapered inwardly and issuitably connected with-the drain-pipe 20. Within the interior of themember I9 is a pair of nested cup- ,like members 2| `and 22,`thesamebeing spaced -to providea ycup-shaped chamber 23. Both therefore,an eifective trap.

of said members are provided with outstanding beveled flanges at theirupper edges which rest one upon the other while the iiange of the outermember rests upon the fiange of the drain member I9. The inner member 22is provided with a plurality of small perforations 24 in its bottom. Thebottom of the outer member 2I is imperforate, but a row of perforations25 extends about and through its side walls some distance above thebottom of the inner member. The water iiowing from the bowl is thusforced to rise within the outer member before it can pass through theperforations 25, and any hair or other matter carried by the water istrapped within the. member 22 or within the space 23 between themembers. The members are not xed in position and can bereadily liftedout, to clear away the hair or other accumulated matter. The structureis.

Leading from the rear into the housing I5 is a pair of supply pipes forthe hot and cold water respectively. One of these pipes,` say thehot-water pipe, is shown at 26 in Fig. 1. The other pipe is shown at 21in Fig. 4. Of course, it is immaterial which is the hot-water pipe. Attheir forward ends, these pipes are connected with a manifold or mixer28. The ilow of the water through these pipes is controlled by valves;

the stems of which project through the upper wall of the housing I5 andare provided with suitable hand grips or levers 29 and 30 respectively.The water for the washing operation is discharged from the mixerforwardly through a down-turned spout 3l in front of the housing andabove the bowl. In the connections between the mixer and the spout is avalve which is normally closed but is adapted to be opened by the wateras it iiows toward the spout. Any suitable connections and valve may beemployed, that shown comprising a nipple 32 which is threaded into themixer 28 and projects through the front wall of. the housing, the spoutbeing screwed onto the nipple, suitable nuts 33 holding the nipple inplace. The forward end of the nipple is provided with a seat for a valve34 which may be a ball, as shown, or any other suitably shaped valvemember which ts upon said seat. That part of the spout which surroundsthel valve is bored or cored to receive a helical spring 35 which iscompressed between the valve and an internal shoulder 36 within thespout. The vspring is relatively weak so that a comparatively slightwaterpressure is suiiicient to open the valve. The valve itself may beformed of any suitable material.

Connected with the mixer or manifold between the supply pipes 26 and 21is a flexible pipe 31 which is looped downwardly and is then extendedupwardly through'an aperture 38 in the upper part of the member I4, thepipe being provided with a ball-like enlargement 39 to hold the pipe inthe looped formation shown in Fig. 4. At its upper or outer end the pipeis provided with a spray-head 40, the ow of the water to it beingcontrolled by any suitable hand-operated valve, as indicated at 4I.

To hold `the flexible pipe taut and to pull it back-after it has ,beenextended, as will be more fully explained, I provide a mobilev weight inthe form of. a sheave 42, the same having a deep peripheral groovemidway between its ends in which the loop o! the pipe reposes. thesheave are parallel and fit between the side walls of a well or casing43 so as to be guided by said walls and be prevented from turninglateral- 'I'he ends of ly; for if the sheave were permitted so to turn,the vertical portions of the pipe would wrap about each other andprevent or limit the outward movement of the pipe. The deep groove inthe sheave holds the pipe centrally positioned in the well 43 and holdsit out of contact with the guide walls of the well. The well may beattached to any conveniently-positioned part of. the apparatus, as by abracket 44 which is fastened to the well and the'housing I5.

As will be seen in Fig. 1, the rim of the bowl is approximatelyrectangular in plan, the side edges being substantially perpendicular tothe attaching member I4. This provides a at, horizontal surface, 45, ateach side of the housing I5 upon which to place soap, glasses or otherarticles which may be employed.

The operation may be briefly described as follows: The valves at 29 and30 having been'respectively adjusted until the eiiluent water at thespout is of the desired temperature the patient vsits or reclines infront of the bowl with the nape of her neck in the notch I6 and her headover the bowl. Her hair is then thoroughly washed. During thisoperation, the valve 4I at the spray-head is closed, and the water opensand passes the valve 34 and flows through the spout'3I. Usually, soapsor other toilet preparations which create a lather, are employed so thatit is necessary that the hair be thoroughly rinsed. The operatorthereupon graspsthe spray-head, pulls it upwardly and forwardly to itsproper spraying position and opens the valve 4I. That relieves thepressure` upon-the valve 34 and allows it to close, thus diverting allthe water to the spray-head. Havingfthoroughly rinsed the hair, allvalves are closed and the sheave-weight is permitted to pull theflexible pipe back into its normal position. Finally, the trap members2I and 22 may be removed, if need be, cleaned and returned to'theirnormal positions. after which the apparatus is ready for' anotherpatient.

As will be noted rfrom Fig. 4, the diameter of the sheave 42 is shcrterthan the transverse dimansion of the guide casing 43. This not onlypermits the sheave to enter the casing but prevents the jamming of theiiexible pipe 31 between the sheave and casing.

If the flexible pipe were drawn out too far it would be bent abruptly atits connection with the manifold or mixer and would be liable to bepulled loose or to start a leak at that point. To prevent that possibleresult, I prefer to provide a readily removable stop. which may beattached to the guide casing to project into the path of the sheave toarrest it before the pipe is thus abruptly bent.

While the invention as described is particularly designed for use inwashing and rinsing the hair, it is obvious that, with slightmodification, it is adapted for other uses. For example, it maybe usedas a kitchen sink, or as an attachment for a kitchen sink, whereindishes are washed and sprayed. In that case, the notch I6 would not beneeded or desirable; but otherwise the structure and operation would besubstantially as shown and described.
